More than two dozen ham operators brushed up on their digital skills at the latest information session, sponsored by Connecticut Region 2 of the Amateur Radio Emergency Service (ARES) this past weekend.
The class focused on digital radio modes that can be used during a disaster, when conventional phone lines and electricity might be cut off, says Douglas Sharafanowich, Region 2 ARES coordinator.
Among the modes discussed was packet radio, which provides error-free transmission and forwarding of text messages, and WinLink2000, a worldwide system of e-mail by radio without the need for Internet.
Both presentations were led by Wayne Gronlund, Connecticut Section Emergency Coordinator.
Also discussed was APRS, the Automatic Packet Reporting System, which uses ham radio to track and control vehicles, people and key assets, over long and short distances.
"These technologies have been in use for several years and are the forerunners of today's familiar Twitter and Instant Messaging," Sharafanowich said. "But, unlike amateur radio, commercial services require a functioning sophisticated communication structure to work."
ARES Region 2 in Connecticut includes towns from Milford to Meriden to Old Saybrook, and is a specialized program of the American Radio Relay League.
The next Region 2 meeting is scheduled for March 10th at Guilford Fire headquarters. The topic will be field programming an amateur radio without a computer.
